''o fla/, 'uf/tmii, '//1 lil/ty concern:

Be it known that l, JOHN G.SiiUs'rnn, acitizen of the United States, residing at Chickaf` sha, in the county of lickens, lndianTerritory,` i have in vented anew and useful riii'e-Slirinker,

ject to improve the construction and produce a device of this character 'simple in operation, easily applied, and by means of which an in-l creased force may be applied without increase of expense or complicationotparts.` l,

\Yit`h theseand other objects in view, whiclr will appear :is the nature of the invention Ais better understood, the saine consists ,in certain noi'el features of constrnction. as. hereinafter full)v described and claimed.

` ln theaccompanying drawings, forming a pai-tof this specilicatioii, and `in which correspending parts are denoted by like designating characters, is illustrated'the preferred l'orin'of embodiment of theinventioncapable of carrying the same into practical operation,

it being understood that the invention is not" necessari li' linii ted thereto, Aas \-'ariousfchanges in the shape,` proportions, and general assem-` blage o f the parts ma)Y be resorted to without `departing freni the principle ofthe invention yor,sacrificing any of its advantages, and the right is therefore reserved ofv making' all the changes and modilieatioi'is,which fairly fall within the scope of the. invention 'and the chiiins made therefor, n n ln the drawings thus employed, Figure 1 'is hin view of the device a .i ilied. Fie'. 3 is a l lk C longitudiinilsectionalview. 1 Fig. iisatranstire 11 when upon the wheel 12, the endsof the chain beingiinitedby spaced links` 1314,V .15 lo, piroted at 1T `18 to` the chainends.

Between the ends of themember l0 asuppoi'ting-frame 19 disposed, lgavii'ig a centrl rg- CLS-2Q :Ulti spaced side recesses '22 23, the side recesses for pivotfillyv supportingthefinner endsfof thek links by pivots 24 "25 passing through the adjacent walls of the recesses.

tral recess andthe side recesses is extendeiil felly and kpi'event lateral displacementof the frame.' Y.

Within the central recess `2() a block 2h is movably disposed, and extending through the head of the frame 19 is a set-screw 29, bearing upon the`V block. Y p y The alternate links of the chain member l() arefoi'med with depending-sides,30,which extend upon. either sideof the tire and effectually prevent late-ral displacement of the chain` -Y At one'or more points in the chain nieinljier substituted for therivets' usuallyv employed foriconnectingtheflinks, sorthat the chain may be lengtheriedyor shortened to adapt it to `wheelsof diiferentsizes. Y y n rl`he pivot members 11.7 '18, whereby the "ably be providedv'itli spacers 39. 33 to inainiative to the links. t,

Ivious that whenithe improved device is zipplied to a tire upon a wheel and the set-,vA Ii'ew 29 i'otatedthe flexible member will be ioicibly'drawn around the tire n and engage it for its whole length andisl'irinly it upon the bolts or rivets;

The device is simple in constriictioi'i,can be manufacturedat small expense, and may be quicklyv adjusted to'ai'iy size of wheel and applied and operated by any person without pre vious skill and ngthe tire. y, i The parts willQpreferablyrr be Vofsteel and will `be proportioned in size to withstand rthe 'strains to which they will be subjected.

l i i f The material of the frame between the cen-` i katZGto embrace lopposite sidesof they tire and lOV the links will be detachable, asbi-v bolts 151,

linksand chainsr ai'e connected, \\'ill,} n'efei Vtain thechains in proper central position reli,

` Bytliis simple arrangement it will be obfV felly of the wheel and draw its ends into Acli'ise` proximity, the tirebeiiig then fastened, :is by y Having thus described my invention` what y without the necessity for heat- Y c 9o connecting the ends of the. flexible member,
